Filed May 19, 1958, Ser. No. 736,013 1 Claim. (Cl. 38-66) This invention relates to padding, and more particularly to a type that is subjected to moisture, heat and pressure, and such as is employed on the rolls of laundry machines and for other purposes. v

One type of such material as used at the present time, is composed of carded asbestos inthe form of a bat and over which is placed a piece of gauze. In some instances these pads are laminated or composed of three or more layers, each of which may be approximately one-half of an inch in thickness. The moisture to which a pad of this nature is subjected by the ironing operation, is intended to be dissipated by the heat from the steam chest. However, when there is more or less continuous feed of linen past the ironing roll bearing the padding, the absorbed moisture is not dissipatedquickly enough, with the result that the padding packs down so that frequent adjustment is required to maintain proper pressure by the rolls.

It is an object of the present invention to provide a pad or padding which will utilize the asbestos as above pointed out, but which will provide a layer of moistureimpervious, heat-reflecting material such as a metallic sheet or foil, for example sheet aluminum or foil, interposed in the asbestos and between the outer faces of the pad, such as between the layers of asbestos. Such Ya metallic layer will thus form a barrier in the pad and will also serve as -a heat reflector tending to reflect heat back through that part of the padding which is interposed between the metallic layer and the surface of the roll that isV positioned adjacent to the steam chest. The layer or layers of lasbestos disposed between the metallic sheet u and the roll will be kept dry; will `not materially pack down thus -maintaining a uniformly-sized roll; willl result in ironing of better quality; will subject the roll covering to less Wear and will require fewer adjustments of the roll.

With these and other objects to be hereinafter set forth arent O Patented Aug. 2, 1960 the metallic foil is arranged closer to the surface 5 than it is to the surface 6. In the application of the pad to a in view, I have devised the arrangement of parts to be described and more particularly pointed out in the claim appended hereto.

In the accompanying drawing, wherein an illustrative embodiment of the invention is disclosed,

Fig. l is a face View, with some of the layers shown fragmentarily, of a section of padding made according to the invention;

Fig. 2 is a sectional View through the padding;

Fig. 3 is a face view of a portion of the metallic layer or sheet, and Y Fig. 4 is a perspective view of a modiiied construction.

In the embodiment of the invention shown in Figs. 1 and 2, the pad or padding is composed of four layers, those indicated at 1, A2 and 3 being preferably of fibrous, heat-resistant nature, such as carded asbestos. These three layers are of more or less uniform thickness, being preferably approximately one-half inch in thickness, although this thickness might be varied considerably. The layer shown at v4 is composed of flexible, moisture-impervious, heat-reflecting metallic sheeting or foil, such as aluminum sheet or foil ranging from .0007 to .001 inY thickness.

The layer foil 4 of aluminum is sandwiched between the layers of asbestos and is preferably located in the resultant bat closer to one surface than to the opposite face. For example, in the embodiment shown in Fig. 2.

roll, the surface 6 is that which is applied next to the roll so that the asbestos layers Z and 3 are interposed between the periphery of the roll and the metallic layer 4, thus providing a substantial thickness of padding between the roll and the metallic sheet. The outermost layer 1 of asbestos is that which contacts the steam chest, the same being, of course, covered by the usual covering.

Dueto the arrangement described, a heat and moisture barrier is introduced in the pad between the layers thereof. This barrier, consisting of the metallic sheet 4, allows the moisture to enter into the portion of the pad next to the steam chest, or `that asbestos layer indicated a 1 and described as he outer layer. The heat-reflecting characteristics of the metallic sheet cause the heat to be reflected back, thus tending to dry the layer 1 while keeping the layers 2 and 3 relativelydry by its moisture-impervious quality. IBy keeping the layers 2 and 3 dry the compacting of these layers is prevented, the resilience of the pad is maintained and numerous other advantages are secured as will be apparent to those skilled in this art.

The addition of the metallic layer to the pad `adds considerable strength and body to it, permitting the pad to be more easily handled and applied to the roll and in addition it materially extends the life of the padding.

The metallic sheet 4 may be maintained between the layers of asbestos in various ways and a simple and effective way can consist in the provision Yof holes in the metallic sheet along the opposite side edges of the sheet as indicated at 7 in Fig. 3. These holes permit the entry of the asbestos fibres forming a locking means to hold the metallic sheet against displacement. Other means for preventing shift of the metallic sheet might be employed.

I have herein stated that the padding might consist of three layers of asbestos with an interposed sheet of metallic or aluminum foil. Ihave also suggested that the metallic sheet might be arranged closer to one face of the padding than to the opposite face. In the embodiment shown in Fig ,4, the metallic sheet is interposed in the middle of the pad, and the asbestos layers, which are two in number are arranged on the opposite sides of the .metallic sheet. Various' other arrangements are possible,

with the thickness of the pad, the number of layers employed and the disposition of the metallic sheet varied to meet individual requirements.

Having thus described a single embodiment of the ineffect than the outer layer, the layer of metallic foil having a plurality of rows of lapertures located adjacent to its marginal edges and spaced from each other, the metallic layer being imperforate between the rows of apertures, the. layers of padding having fibres entering into the apertures to thereby restrain movement of the metallic layer relatively to the layers of padding.
